Chapter 13: Surgical Therapy for Glaucoma
Cataract Surgery in the Glaucoma Patient
After surgery for visually significant cataract, patients with ocular hypertension or glaucoma may have a reduction in IOP.
In the Ocular Hypertension Treatment Study (see Chapter 7), 42 patients underwent cataract surgery while enrolled in the control arm of the study. These patients were compared to patients in the control arm who did not undergo cataract surgery. At 36 months, the average IOP reduction in patients who had cataract surgery was 16.5%. Moreover, 40% of eyes that underwent cataract surgery had a ≥20% reduction in IOP at 36 months. Conversely, the mean IOP in eyes that did not undergo cataract surgery was unchanged at 36 months.
